From the belvedere to the quarry, two complementary viewpoints. A guide from Atemporelle and a professional from Carrières Roy will show you all the site has to offer (landscape, geology, history) and explain how the Roy quarry works, France?s first solid rock aggregate extraction site. Come and discover all the facets of this site. The visit, by coach, takes you to the Pâtis lookout for a breathtaking panoramic view of the quarry and landscape; and continues on the site to discover the area currently being mined, with its working faces, industrial facilities and railroad line, and to understand the various stages in the manufacture of aggregates before their storage and transport. A unique opportunity to meet professionals who love their work! Reservations required.
